Title: Alternative Qualitative Fit Testing Method for N95 Equivalent Respirators in the Setting of Resource Scarcity at the George Washington University Document date: 2020_4_11
ID: 3khv6yrc_19
Snippet: 4.0 Discussion: The process described above demonstrated that it is possible to emulate a clinical qualitative fit test using easily available materials. The sensitivity test was detectable for all tests of all masks and all subjects, suggesting the atomizer and saccharin solution functioned comparable to a nebulizer for this purpose similar to clinically used Saccharin or Bitrix in qualitative fit tests. The N95 respirator has been approved by O.....
Document: 4.0 Discussion: The process described above demonstrated that it is possible to emulate a clinical qualitative fit test using easily available materials. The sensitivity test was detectable for all tests of all masks and all subjects, suggesting the atomizer and saccharin solution functioned comparable to a nebulizer for this purpose similar to clinically used Saccharin or Bitrix in qualitative fit tests. The N95 respirator has been approved by OSHA and US NIOSH, functioning as high efficiency particulate filter against coronavirus, and a positive control for this study. (OSHA 29CFR1910.134) The 3D Printed Reusable N95 Respirator had been previously tested in employee health, so it also served as a positive control for this purpose.
